How to get a list of Jobs created by ScaledJob?

Question

How can I get a list of Kubernetes Jobs created by a particular ScaledJob object?

Answer 1

When KEDA creates Jobs as a result of a ScaledJob object, it also adds a set of labels to the Job.

labels := map[string]string{
    "app.kubernetes.io/name":       scaledJob.GetName(),
    "app.kubernetes.io/version":    version.Version,
    "app.kubernetes.io/part-of":    scaledJob.GetName(),
    "app.kubernetes.io/managed-by": "keda-operator",
    "scaledjob.keda.sh/name":       scaledJob.GetName(),
}

This allows you to use kubectl get jobs with the -l, --selector='' option to filter jobs by label.

-l, --selector='':
    Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching
    objects must satisfy all of the specified label constraints.

For example, for a ScaledJob named foo:

$ kubectl get jobs --selector='scaledjob.keda.sh/name=foo'
NAME        COMPLETIONS   DURATION   AGE
foo-cjgds   1/1           7m11s      27m
foo-rwrtx   0/1           41m        41m

Likewise, you can get all Jobs created by KEDA by selecting based on the app.kubernetes.io/managed-by label:

$ kubectl get jobs --selector='app.kubernetes.io/managed-by=keda-operator'
